Unit Inoperable After Attempted OS Update

Common Causes

We have seen two primary causes for this. Fortunately it should be a simple fix. Some important things to keep in mind:

Not using the correct OS Update Kit.

Be sure to use the correct OS update to install in your unit. The SP4-8 and SPS4-8, though similar in name and indeed function, use DIFFERENT OS update packages. Using the wrong OS update kit is primary cause behind this issue in cases we have seen so far.
